Abstract

The persistence and dry forage production of nine accessions (8 Hemarthrias and one Cynodon) in mob grazing were measured during a 387-day period. During the short day season, accession H. altissima USDAPI 364888 produced the highest dry forage yield, but did not differ significantly (P<.05) from the others except for H. altissima USDAPI 364873 and 364875. During the long-day season, H. altissima USDAPI 364888 again produced the highest dry forage yield, not differing significantly (P<.05) from H. altissima 364873, 364875 and 409744 and C. plectostachyum 341818. For the whole 387-day period, accessions H. altissima USDAPI 364888, 364873 and 409744 and C. plectostachyum 341818 showed excellent yields in terms of consumed forage. However, no significant differences (P<.05) were observed among accessions during the period mentioned. Similarly although no significant differences (P<.05) were observed in terms of weed infestation percentages, accessions H. altissima USDAPI 364875 and C. plectostachyum USDAPI 341818 had higher weed infestation percentage than the other accessions. In terms of leaves to stem ratios C. plectostachyum USDAPI 341818 produced the highest percentages without differing significantly (P<.05) from H. altissima USDAPI 364873 and 379617.
